IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent No. 153,157, dated July 21,1874 application filed December 15, 1873.

delivery-tube, and extending downward into the cup. Upon thespring-bottom of the cup there is secured asmall wire or plunger, whichpasses through a small hole at the lower end of the strainer, and upwardto near the efl'lucut end of the spout, and within said spout,-

as hereafter more fully described.

The accompanying drawing is a vertical and central section of an oil-canwhich embodies our invention.

A designates the spout, and B the cup, which are screwed together, sothat the spout may be unscrewed for the purpose of filling the cup, allas in the ordinary oiler. To the base of the spout A we secure a conicalstrainer, a. This can be made of wire-cloth, perforated sheet metal, orother suitable and ordinary material for strainers. We prefer to makethe strainer a in conical form, and to have it extend downward from thebase of the spout, so that it can be readily cleaned when withdrawn fromthe cup. This strainer may be a straight cylinder closed at the lowerend, instead of the conical form; but it must be of such a size that itwill readily pass through the mouth of the cup B; and its lower endshould be provided with a small hole of a size sufficient to admit theplunger'hereinafter described. Upon the inside and near the center ofthe spring-bottom C we secure a wire or plunger, 0, which plunger is ofa length nearly equal to the depth of the cup and spout, and

passes up through the small hole at the lower end of the strainer a, andinside of the spout, to near its end.

The strainer will prevent specks, dirt, or sediment from entering thelower end spout, and by following upward clogging its delivery.Sometimes, however, the eflflu'ent end of the spout comes in contactwith dirt, &c., which clogs the delivery. When the spring-bottom isdepressed to eject the oil, as indicated by broken lines, the plungerwill move longitud inally within the tube, so as to project a littlebeyond its end; and when the spring-bottom is released the plunger drawsback with it. This movement will loosen the dirt or matter in theeffluent end of the tube, so as to allow, by the combined action of thestrainer and plunger, a free discharge of the oil.

In an oil-can of the class described, the combination of the strainerand plunger, substantially as described, and for the purpose set forth.
